HEATING DRUM.

Application filed June 3,

This invention relates to improvements in heating drums.

It is the primary object of the present invention to provide a heating drum which. will utilize for the heating of a conducted fluid, smoke and gases ofcombustion from a furnace prior to the passage of the smoke into the chimney.

A further object of the invention is to provide a heating drum which will economize in the useof fuel, by utilizing heat units which ordinarily escape through the smoke pipe, permitting the use with a given furnace of several more registers or radiators than can ordinarily be used.

A further object of the invention is to provide a heating drum in which the smoke is passed back and forth through tubes and through a large body of confined fluid which is subsequently conducted for heating purposes. y

7 A further object of the invention is to provide a heating drum of the class described in which the smoke tubes are readily accessible and may be reached in order to be cleaned of soot and other deposits.

A further object of the invention is to pro vide a heating drum of compact design which may be readily connected with any type of heating furnace.

A further object of the invention is to provide a heating drum which is of very simple construction, is inexpensive to manufacture and install, is efficient in use, is strong and durable, and is well adapted for the purpose described.

With the above and other objects in view the invention consists of the improved heating drum, and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a side view of the heating drum showing its connection with a furnace, a chimney, and several heating registers;

Fig. 2 is an enlarged longitudinal sectional view of the heating drum;

Fig. 3 is a cross-sectional view thereof taken on line 33 of Fig. 2; and

i Fig. 4: is an end view thereof taken on line 44 of Fig. 2.

Referring now more particularly to the drawings it will appear that the numerals 6 and 7 indicate a pair of end drums which are held in spaced relation by a plurality of smoke 1927. Serial No. 196,313.

tubes 8 which are secured at their ends to the inner faces of the drums and communicate with the interiors thereof.

Secured to opposite sides of the drums are the upper end portions of two pairs of supporting legs 9 which support the drums and connected tubes above the floor. Also, the drums and connected tubes are enclosed and covered by a casing 10 which is spaced from the ends and top ofthe drums and extends to the floor. Openings are formed in the opposite lower side portions of the casing and said openings are provided with connections 11 and 12 to which are attached the end portions of cold air pipes 13 and 1 1. The top portion of the casing is also formed with openings and connections 15 and 16 extending there from to which are attached warm air pipes 17 and 18. y

The upper portion of the outer face of one of the drums, as 7, is provided with an opening from which a connection 19 extends outwardly through the adjacent end of the casing and has attachedthereto the end portion of a smokepipe 20 leading from a furnace 21. The other drum 6'has a similar opening in the lower portion of its outer face and a connection 22 extends therefrom through the adjacent end of the casing and is attached to an exhaust pipe 23 which extends to a chimney 24.

There is also provided in the outer face of the drum 6 an upper opening from which a collar 25 extends exteriorly through the casing and the outer end portion is closed by a removable cover 26. The other drum 7 has a similar opening and collar 27, only opening into its lower portion, and the open end of said collar is also closed by a removable cover 28. Said collars, opening into the drums, afford access to a plurality of smoke tubes to permit the same to be cleaned of deposits. The drum 6 is divided horizontally by a partition 29 immediately above the opening for the connection 22, while the drum 7 has a similar dividing partition 30 in its upper half, immediately below the opening for the connection 19.

In use, the heating drum is connected with a furnace and a chimney by means of the pipes 20 and 23, as shown in Fig. 1. The cold air pipe is extended to an inlet for air while the hot air pipes extend to suitable registers 31 situated where desired in a buliding. The smoke and gases of combustion from the furnace pass into the upper portion of the drum 7 lromthe smoke pipe 20, and because of the partition 30 the smoke and gas pass through the upper tubes 8 to the drum 6 and then back to the drum 7 through some 01 the intermediate tubes and then is returned to the drum 6 through the lower tubes, and from the drum 6 it is expelled to the chimney through the pipe 23. Cold air enters the loWer portion of the easing from the pipes 13 and 14: and is directed by an angular baffle plate 32 upward- V ly, circulating around and between the tubes 8, as indicated by the arrou' 's in Fig. 3. As hot smoke is coi'istantly circulating back and forth through all ot said tubes the air in the casing absorbs and takes heat therefrom, which is ordinarily Wasted, and said air,

rising as it is heated. leaves through the pipes a pair of verticallydispo'sed drums there- Within and spacedfrom the casingga plurality of horizontally extending smoke tubes connecting; said drums and communicating with the interiors thereof, a short pipe comv, m'unicating With each drum and extending through the casing, said pipes affording access to the tubes for cleaning purposes, a removable cover for the outer end of each of said short pipes, a furnace smoke pipe entering the upper portion oi one of the drums through the casing, the interior of said drum having a horizontal partition below said smoke pipe opening, a chimney smoke pipe entering the lower portion of the other drum through the casing, the interior oi said drum having a horizontal partition above said smoke pipe opening, a fluid inlet pipe entering the lower portion of the easing, and a fluid outlet pipe extending from the upper portion of the casing.

2. A heating device, comprising a casing, a pair of drums therewithin and spaced from the casing, a plurality of smoke tubes connecting said drums and comnmnicating with the interiors thereof, a short pipe communieating With each drum and extending through the casing, each pipe ali'ording uccess to a plurality of tubes for cleaning purposes, a removable cover for the outer end of each of said short pipes, a furnace smoke pipe entering one of the drums through the casing, a chimney smokcpipe entering the other of said drums through the casing and diagonally opposed to said furnace smoke pipe, a fluid inlet pipe entering the lower portion of the casing intermediate its ends, and a fluid outlet pipe extending from the upper portion of the casing.

In testimony whereof, I aflix my signature.
